This is a mash that I've been tryng to make for quite a long time, actually. It just so happened that the tech for separating vocals and instruments got better enough to actually make a big difference in how the instrumental sounds, as when I tried to make this before, it didn't sound good.
And if you need more info, PXNDX (formerly known as Panda) is part of the Avanzada Regia musical movement from my hometown, just like El Gran Silencio.
